About Math Cages
Math Cages is a number puzzle that mixes sudoku-style logic with arithmetic, like the KenKen puzzles in newspapers. On a 4 by 4 grid you use the numbers 1 to 4, and every row and every column must hold each number once.
The grid is split into cages with thick lines. Each cage has a target and a sign: 7+ means its numbers add up to 7, 12× means they multiply to 12, 2− means one minus the other is 2, and 3÷ means one divided by the other is 3. There are 60 puzzles in five packs, from tiny 3 by 3 grids with only adding up to 6 by 6 grids with all four signs.
It is great practice for times tables, factors and mental maths, because you keep asking which numbers could make a target. Pencil notes, clash warnings and hints help when you are stuck, and solving without hints wins 3 stars. A robot checked that every puzzle has exactly one answer.
Best for ages 8+
